Marco Wagner updated IMAGING-188:
---------------------------------
Description:
I needed larger icons of icns files, so I edited the source code.
See Pull Request.
https://en.wikipedia.org/wiki/Apple_Icon_Image_format
was:
I needed larger icons of icns files, than currently extracted with the Apache
Commons Imaging ICNS Image Parser/ICNS Decoder.
So I edited the Source Code:
In case an icns element is a PNG (depends on 0-4th byte [header]),
the bytes can be put in a ByteArrayInputStream and then read by ImageIO.read,
that returns the BufferedImage needed.
Then it can be added to the list of List<BufferedImage> in
IcnsDecoder#decodeAllImages().
InputStream in = new ByteArrayInputStream(imageData);
BufferedImage image = ImageIO.read(in);
To the enum IcnsType I added:
ICNS_256x256_32BIT_ARGB_IMAGE("ic08", 256, 256, 32, false),
ICNS_512x512_32BIT_ARGB_IMAGE("ic09", 512, 512, 32, false),
ICNS_1024x1024_32BIT_ARGB_IMAGE("ic10", 1024, 1024, 32, false);

No need for Rle24Compression.decompress() or decode32BPPImage().
I can upload the code somewhere, please tell me how to do.
